Sir John Tenniel (28 February 1820 – 25 February 1914) was an English illustrator. He drew many topical cartoons and caricatures for Punch in the late 19th century, including his most famous political cartoon, Dropping the Pilot, but is best remembered today for his illustrations to Lewis Carroll’s Alice’s Adventures in Wonderland and Through the Looking-Glass.

In 1865 he illustrated the first edition of Alice in Wonderland. The first print run of 2,000 was shelved because Tenniel objected to the print quality; a new edition, released in December of the same year but carrying an 1866 date, was quickly printed and became an instant best-seller, securing Tenniel’s lasting fame in the process. His illustrations for both books have taken their place among the most famous literary illustrations ever made.
